If they find a 3-down NT, they should go for it.
Or a big ILB that can take on linemen as well as having the smart and the ability to cover TEs.
Or a big safety that can blanket a TE, allowing Quin to be the fifth DB.
Or a monster OT, allowing Newton to be the swing tackle.
If they don't like Brandon Brook enough to be a starter, they need to find a good one there.

As much as I like some players in the draft at other position, I don't think they can add enough overall value to the team to make it more complete.
